Embodiment 1
[0025] This embodiment proposes a multi-thread-based ID card reading method, and an ID card reader is used in a business management software system to trigger a corresponding business. The main realization process of the ID card reading method specifically includes the following steps:
[0026] Step 1, the card reader assistant class provides the card reader connection state change event;
[0027] Specifically, the card reader assistant class provides the card reader connection state change event, and the corresponding processing is triggered when the card reader connection state changes. remind;
[0028] Step 2, the card reader assistant class provides ID card reading events;
[0029] Specifically, the card reader assistant class provides ID card reading events, and triggers corresponding processing when ID card information is read, and the program searches for data, saves ID information, or triggers other related services;
[0030] Step 3, multiple functions jointly regis...
Embodiment 2
[0035] A multi-thread-based ID card reading method proposed in this embodiment is another specific implementation of the present invention. On the basis of the multi-thread-based ID card reading method in Embodiment 1, an ID card is used for reading The technical solution and technical features of this embodiment are described in detail by taking the device searcher as an example.
[0036] First, the card reader helper class provides the card reader connection state change event;
[0037] Specifically, the card reader assistant class provides a registration button to display the connection status, and the system displays the card reader connection status on the button in the form of different icons; the card reader assistant class provides registration custom operations, and the card reader connection status occurs. It will be triggered automatically when it changes;
[0038]
[0039]
[0040] Then, the reader helper class provides the read to ID event;
[0041]
